Upgrade 2.2.2->2.2.8 caused to increase of queue lenght

[IvanBayan]

Hello.
Yesterday i decided to upgrade zabbix from 2.2.2->2.2.8, later i noticed that trigger "More than 100 items having missing data for more than 10 minutes" was fired.
Queue grown from ~10 to over than 1000 .
I have near 80 hosts most of them queried over snmp, before that update i never faced with high load of zabbix or poor performance, i attached screenshots.
What am i doing wrong?

Hi,

This is because your devices do not support SNMP bulk requests (introduced in Zabbix 2.2.4).

https://www.zabbix.com/documentation/2.2/manual/config/items/itemtypes/snmp

To fix that please set EnableSNMPBulkRequests=0 (add such line if you don't have it now) in your zabbix_server.conf file and restart the server.

Best Regards,

My hosts queried via a zabbix proxy, i think that it can be caused by SNMP bulk request and tried to set Enable SNMP Bulk Requests=0 on proxy side, but nothing changed. Is i need to made same changes on the server?

You can set EnableSNMPBulkRequests=0 both on server and proxy.

Then wait a while to see if the queue drops.
